I am not sure if I have understood your question correctly. Do you mean to say that you want to build form with the fields details from your MySQL data base?
Unfortunately it is currently not possible to build form with the data from your own DB. If you want to send your form's submission data to your's MySQL database, there are multiple options available to achieve your requirement:
1. You can post your form's submission data to your own page by enabling the "Send Post Data" in your form preferences and then redirect to your own thank you page where you can read the submission data. The following guide should help you: http://www.jotform.com/help/213-Send-POST-Data-From-JotForm-Using-PHP-in-Custom-Thank-You-Page
2. You can take advantage of our Zapier integration app as well. Take a look at here: http://apps.jotform.com/app/zapier_integration You may also like to check this which should help you: https://zapier.com/zapbook/jotform/mysql/4061/add-jotform-submissions-to-mysql/
Hope this helps.
